Had it twice, first time loss of about 80%, 2nd time 100%loss of smell, 90-100%taste.
both came back within a week or two.
I took NAC, vit D, vit C and zinc (can Google studies for all of these)
I’ve also tested my vit D levels every three months since the pandemic started. To begin with I was severely deficient (with no symptoms, only tested bc of the pandemic, private) and the gp gave me 8x normal dose of 10 for 3 months to get it back to normal
first time I suppose bc of the low vit D, though I was already in treatment, but not back to normal levels, covid floored me the first day, had a rough 3-4 days after and then in recovery, but still weak.
I kept checking my oxygen levels too with the oxymeters, had them at 98-99% until the 2nd or 3rd day when they went to 96-97. (Below 95 you need to call gp or 111 and they might refer you to hospital, and any 1 under is direct hospitalisation)
im still testing my vit D levels, there are close to 100, so very good. The 2nd time I got covid I wouldn’t have known without the loss of smell and taste, only had a stuffy nose.
od recommend everyone checks their vit d levels, it might help in recovery or if you get it again. You might have mos symptoms like me if you’re deficient.
ah, after the first covid my levels who were improving, dropped again, so covid ate into that.
